One difference that I'm aware of is that the 1.1 version has the dos 
command that 1.0 doesn't.  This makes booting os9 as simple as 
inserting the disk and typeing 'dos'.

Another difference is in one of the jump tables at the beginning of 
the rom, where the 1.0 version violated tandy's own guidelines about 
pointer useages.  I ran into this when converting Jake Commanders 
'ChromKey' utility to run on 1.1.  That was waaaay back up the 
log. :-)
